想用Html.fromHtml(String, ImageGetter, TagHandler)这个方法将html文档解析。
通过重写handleTag(boolean opening, String tag, Editable output, XMLReader xmlReader)来解析自定义标签，但发现没办法读取标签中的属性。网上的找了很多方法试了都是没有用的。查了HTML的源代码，发现内部都是通过 attributes.getValue("", "属性名"); 来取得属性，但是attributes 并没有传递出来。于是又开始在网上找如何取得这个attributes。
找了很久很久之后，最后在stackoverflow上找到了解决方法，

public void handleTag(boolean opening, String tag, Editable output, XMLReader xmlReader) {
if(tag.equalsIgnoreCase("myTag")) {
if (opening) {
Field elementField = null;
try {
// get the private attributes of the xmlReader by reflection by rekire
///questions/6952243/how-to-get-an-attribute-from-an-xmlreader?rq=1
elementField = xmlReader.getClass().getDeclaredField("theNewElement");
elementField.setAccessible(true);
Object element = elementField.get(xmlReader);
Field attsField = element.getClass().getDeclaredField("theAtts");
attsField.setAccessible(true);
Object atts = attsField.get(element);
Field dataField = atts.getClass().getDeclaredField("data");
dataField.setAccessible(true);
String[] data = (String[])dataField.get(atts);
Field lengthField = atts.getClass().getDeclaredField("length");
lengthField.setAccessible(true);
int len = (Integer)lengthField.get(atts);
String myAttributeA = null;
String myAttributeB = null;
for(int i = 0; i < len; i++){
//这边的src和type换成你自己的属性名就可以了
if("src".equals(data[i * 5 + 1])) {
myAttributeA = data[i * 5 + 4];
} else if("type".equals(data[i * 5 + 1])) {
myAttributeB = data[i * 5 + 4];
}
}
Log.i("log", "src: " + myAttributeA + " type: " + myAttributeB);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
}
